OTU Delimitation with Earthworm DNA Barcodes: A Comparison of Methods

Diversity, 2022
Although DNA barcodes-based operational taxonomic units (OTUs) are increasingly used in earthworm research, the relative efficiency of the different methods available to delimit them has not yet been tested on a comprehensive dataset.

DNA Barcoding and Species Delimitation for Dogfish Sharks Belonging to the Squalus Genus (Squaliformes: Squalidae)

Diversity, 2022
The Squalus genus comprises a group of small demersal sharks occurring circumglobally, popularly known as dogfish sharks. This genus exhibits a conserved morphology, thus making correct morphological identification difficult.

ASAP: assemble species by automatic partitioning

Molecular Ecology Resources, 2020
Here, we describe Assemble Species by Automatic Partitioning (ASAP), a new method to build species partitions from single locus sequence alignments (i.e., barcode data sets).

DNA barcoding elucidates the population genetic diversity of venomous cobra species (Reptilia: Elapidae) in Indo-Bangladesh region

Mitochondrial DNA. Part B. Resources, 2020
The DNA barcode data of venomous cobra species (Naja naja and Naja kaouthia) are limited in the global database, especially from India and Bangladesh. Owing to the rapid success of DNA barcoding for discriminating a variety of species around the world ...

DNA Barcoding and Phylogenetics Relationship of Pangasiid Catfishes in Peninsular Malaysia Revealed the Impacts of Aquaculture on the Native Species Conservation

Hydrobiology, 2023
Pangasiids are an economically significant group of catfish, and many pangasiids are threatened in the wild from anthropogenic pressures, including increases in fishing pressure, habitat degradation, and improperly managed aquaculture practices.

Cryptic speciation in populations of the genus Aphyocharax (Characiformes: Characidae) from eastern Amazon coastal river drainages and surroundings revealed by single locus species delimitation methods

Neotropical Ichthyology, 2021
Recent studies in eastern Amazon coastal drainages and their surroundings have revealed new fish species that sometimes exhibit little morphological differentiation (cryptic species).

To be or not to be… Integrative taxonomy and species delimitation in the daddy long-legs spiders of the genus Physocyclus (Araneae, Pholcidae) using DNA barcoding and morphology [PDF]

ZooKeys, 2022
Integrative taxonomy is crucial for discovery, recognition, and species delimitation, especially in underestimated species complex or cryptic species, by incorporating different sources of evidence to construct rigorous species hypotheses.

Interrogation of earthworm (Clitellata: Haplotaxida) taxonomy and the DNA sequence database

Journal of Asia-Pacific Biodiversity, 2021
The DNA sequence database assists us with great potential in species identification because it is practical and affordable to perform. More often, the identification using molecular data helps to identify morphologically variable individuals of same ...
